You may manage your Munki clients using a general manifest (e.g., support_staff), but you sometimes want some more control over also managing installations for individual users without always specifying the serial number as a condition in a manifest.

The most popular tool for this is Munki Enroll, which automatically creates individual manifests with the larger manifest as an included manifest.

I also wrote a tool called MunkiBulkEnroll to do a bulk (non-automatic) enroll, in case you want to tweak names not based on a strict algorithm.
